I don't know about that...
If there's one thing I've learnt, is never underestimate little girls...
Take Nanoha for example, back in the first two episodes of season one, I bet nobody would expect her to grow from that, to someone who nukes anything that doesn't go her way without (
much) hesitation...
If that doesn't convince you, remember that the scariest thing in any horror game/movie is the "little girl"...
